Halo lights on T/A
Seems to me as if it'd be very hard, never heard / seen of a kit or any kind of bulb for it, not saying their isn't one out there. I know there are quite a few HID kits made, but if you want a faster answer try posting this in the Appearance & Detailing section, unless a mod moves it. Also try the search bar ^ there. Good luck with the search though and welcome to the boards. 
EDIT: Also need a few more specifics..i.e. year of T/A

Thats all autozone had for me to buy when my headlight went out. They're not the bright blue ones im thinking your talking about, but they have a shade of blue to them and say halogen on the box. 12$ bucks a light. On the t/a you have to buy the whole headlight you cant get just the bulbs because i was wanting the same and thats as close as they could get.
U can both HID kits for the fogs and lows for $30/piece from DDMtuning. ull have to buy new low beam headlight housings from LMCtruck. Do a search on the write up for this. Ull have about $125 in all of it...also if u go with the LMC housings u need a 9006 bulb. as far as halos, u could probably put the headlight in the oven at 250degrees for about 5 min then try to separate the lens from the housing. Then buy a CCFL halo, a small one, and epoxy it inside then run ur wires through the top or bottom of the housing by drilling a small hole then rtving it. That's what I did on my motorcycle lights. Minus the drilling.
